- title: Common Properties for Serial AT attachment (SATA) controllers
- maintainers:
- - Linus Walleij <linusw@kernel.org>
- description: |
- This document defines device tree properties common to most Serial
- AT attachment (SATA) storage devices. It doesn't constitute a device tree
- binding specification by itself but is meant to be referenced by device
- tree bindings.
- The SATA controller-specific device tree bindings are responsible for
- defining whether each property is required or optional.
- properties:
- $nodename:
- pattern: "^sata(@.*)?$"
- description:
- Specifies the host controller node. SATA host controller nodes are named
- "sata"
- "#address-cells":
- const: 1
- "#size-cells":
- const: 0
- dma-coherent: true
- patternProperties:
- "^sata-port@[0-9a-e]$":
- $ref: '#/$defs/sata-port'
- description: |
- DT nodes for ports connected on the SATA host. The SATA port
- nodes will be named "sata-port".
- additionalProperties: true
- $defs:
- sata-port:
- type: object
- properties:
- reg:

- description:
- The ID number of the SATA port. Aside with being directly used,
- each port can have a Port Multiplier attached thus allowing to
- access more than one drive by means of a single SATA port.
